Hi paola, telnet is not needed anymore, fortunately
Currently the screen size of 1024x758 is hardcoded in the file that manages touch events. So as another user reported, on the Touch there's a huge offset between where you touch and what you get. I think it will be the same on the mini. However, just follow the instructions on post #6 and report

that telnet is not needed is a huge relief, as that looks a tad beyond my limits!
I will try tonight and report back, thank you for porting this!
